Description

1262516 (1) IX. Description of the invention [Technical field to which the invention pertains]

The present invention relates to a method for producing a conductor paste for laminated ceramic electronic parts and a laminate unit for laminated ceramic electronic parts. In particular, the present invention relates to a binder which does not dissolve a layer adjacent to an electrode layer. Further, it is possible to reliably prevent the conductive paste of the laminated ceramic electronic component from being short-circuited and the method of manufacturing the laminated ceramic unit for the laminated ceramic electronic component which can reliably prevent the short-circuit defect of the laminated ceramic electronic component. [Prior Art] In recent years, with the miniaturization of various electronic devices, it is required to reduce the size and performance of electronic components mounted on electronic devices. Laminated ceramic electronic components such as laminated ceramic capacitors are also strongly required to increase lamination. The number and lamination units are thinned. When manufacturing a laminated ceramic electronic component represented by a laminated ceramic capacitor, first, a ceramic powder; a binder such as an acrylic resin or a butyral resin; a phthalic acid ester, an ethylene glycol, a hexanediol, A plasticizer such as a phosphate ester; and an organic solvent such as toluene, methyl ethyl ketone or acetone are mixed and dispersed to prepare a dielectric paste for a ceramic green sheet. Next, the dielectric paste is applied onto a support sheet formed of polyethylene terephthalate (PET) or polypropylene (pp) by an extrusion applicator or a gravure coater or the like. The film is dried by heating to make a ceramic raw sheet. Further, a conductor powder such as nickel and a binder are dissolved in a solvent (2) 1262516 such as a masked alcohol to prepare a conductor paste, and a conductor paste is printed on a ceramic green sheet in a specific pattern by a screen printing machine or the like. The electrode layer is formed by drying. When the electrode layer is formed, the ceramic green sheet forming the electrode layer is peeled off from the support sheet to form a laminate unit including the ceramic green sheet and the electrode layer, and a desired number of laminate units are laminated, which is obtained by pressurization. The laminate is cut into a wafer shape to form a green wafer.

Finally, the binder is removed from the green wafer, and the green wafer is fired to form an external electrode. The laminated ceramic electronic component such as a laminated ceramic capacitor is required to be miniaturized and high-performance in terms of electronic components, and the laminated ceramic is currently determined. The thickness of the ceramic green sheet of the interlayer thickness of the capacitor must be 3 μηι or less, and it is required to laminate 300 or more of the laminate unit including the ceramic green sheet and the electrode layer. SUMMARY OF THE INVENTION [Problems to be Solved by the Invention] However, the electroconductive paste which is prepared by using the most widely used terpineol as a solvent for a conductor paste, which is used for printing, is widely used in printing. When the butadialdehyde resin is used as a ceramic green sheet for a ceramic green sheet adhesive, when the electrode layer is formed, the ceramic green sheet binder is dissolved by the terpineol in the conductor paste, so that the ceramic green sheet is formed. Swelling or partial dissolution causes pinholes or cracks in the ceramic green sheets to cause short-circuit defects. In order to solve this problem, it is proposed to use a hydrocarbon solvent such as kerosene or decane-6-(3) 1262516 as a solvent for the conductor paste, but a hydrocarbon solvent such as kerosene or decane cannot be dissolved for bonding of the conductor paste. Since the hydrocarbon component solvent such as kerosene or decane cannot completely replace the solvent such as terpineol used in the past, the solvent in the conductor paste still has a certain amount of the butadialdehyde resin for the ceramic green sheet binder. The degree of solubility, when the thickness of the ceramic green sheet is extremely thin, it is difficult to prevent pinholes or cracks in the ceramic green sheet, and the hydrocarbon solvent such as kerosene or decane has a lower viscosity than the terpineol. There is a problem that the viscosity of the conductive paste% material is difficult to control. In addition, Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. A terpene solvent such as a phenolic acetate ester replaces the conductor paste of terpineol, but a terpene solvent such as hydrazine terpineol or dihydroterpene alcohol acetate such as dihydroterpineol is still The butadialdehyde resin of the ceramic green sheet adhesive has a certain degree of solubility. When the thickness of the ceramic green sheet is extremely thin, it is difficult to prevent pinholes and cracks in the ceramic green sheet. Japanese Laid-Open Patent Publication No. 2002-27045 No. 6 discloses that a conductor paste containing an isobornyl acetate solvent having a substantially insoluble % deuterated resin is printed on a binder containing a butyral resin. On the ceramic green sheet, a laminated ceramic electronic component is formed to form an electrode layer, and a bonding agent using ethyl cellulose as a conductor paste is disclosed, but an adhesive containing ethyl cellulose contains an isobornyl acetate solvent. The conductor paste has low viscosity and high fluidity. Therefore, when a conductive paste is printed on a ceramic green sheet using a screen printing machine, the conductor paste is oozing out from the screen plate and cannot be printed ( 4) 1262516 electrode layer, and the pattern of the printed electrode layer is easily bleed. Therefore, the present invention does not dissolve the binder contained in the layer adjacent to the electrode layer, and can reliably prevent the short-circuit defect of the laminated ceramic electronic component and provide a conductive paste excellent in printability. Another object of the present invention is to provide a method for producing a laminate unit for laminating ceramic electronic parts capable of forming a desired electrode layer, which can reliably prevent short-circuit defects in laminated ceramic electronic parts.

[Means for Solving the Problems] In order to achieve the above object of the present invention, the present inventors have found that the use of an ethylcellulose having a weight average molecular weight of MWL containing a weight ratio of X: (1-X) and a weight average molecular weight is found. MWH ethyl cellulose binder (MWL, MWH and X series are selected to make X * MWL + ( 1 -X) * MWH 145,000 ~ 215,000) and selected from isobornyl acetate, dihydro hydrazine base Methyl ether, terpine methyl ether, α-terpine acetate, dihydrocarvyl acetate, I-menthone, I-capry acetate, I-perillate acetate and I- A solvent in which at least one of a group of carvyl acetates is prepared, and when the conductor paste is prepared, not only a conductive paste having a viscosity suitable for printing can be prepared, but also a binder of the conductive paste can be dissolved as needed. The conductor paste is printed on a ceramic green sheet containing a butyral resin as a binder. Even if an electrode layer is formed, the ceramic green sheet contains a binder which is not contained in the conductor paste. And dissolve, therefore, even if the thickness of the ceramic green sheet is extremely thin, it can be surely prevented The ceramic green sheet to produce a crack or pinhole. (5) 1262516 The present invention is based on the above-described findings, and therefore the object of the present invention can be achieved by the following electrical conductor paste, which has a white color: X: The weight ratio of ethyl cellulose of weight average molecular weight to ethyl cellulose of weight average molecular weight MWH (select MWl, MWh and χ make x*MWl+(1_x) *MWh

It is 145,000 to 215,000) and is selected from the group consisting of isobornyl acetate, dihydrofurfuryl methyl ether, terpine methyl ether, ethyl acetate, dihydrocarvyl acetate, and I. a solvent of at least one of a group consisting of menthone, I-mercaptoacetate, perilla acetate, and ζ _ 香 乙酸 acetate. The above object of the present invention can also be attained by the following method for manufacturing a laminate unit for laminating ceramic electronic parts, which system comprises: a weight average molecular weight M WL containing a weight ratio of Χ : ( hX ) A binder of ethyl cellulose with ethyl cellulose having a weight average molecular weight of MWH (selecting MWL, MWH and X to make X*MWL+(:l_X) *MWH become 145,000~2 15,000) and selected from isobornyl B Acid ester, indoline methyl ether, terpine methyl ether, α-fluorenyl acetate, dihydrocarvyl acetate, I-menthone, I-capry acetate, I - a conductive paste of at least one solvent of a group of perilla acetate and I-carvyl acetate, which is printed on a ceramic green sheet containing a butyral resin as a binder in a predetermined pattern to form Electrode layer. According to the present invention, a conductive paste having a viscosity suitable for printing can be prepared, and an electrode layer can be formed not only as needed, but also a conductive paste can be printed on a ceramic green sheet containing a butyral resin as a binder. When the electrode layer is formed, the ceramic green sheet contains the binder without the conductor -9- (6) (6)

1262516 The solvent contained in the paste dissolves. Therefore, the ceramic green sheet does not swell or partially dissolve. Even if the thickness of the ceramic green sheet is extremely thin, it does prevent pinholes or cracks in the ceramic green sheet. In the present invention, it is preferred to select MWL, MWH and X by making X*MWL+(1-X)*MWH 15 to 205,000. In the present invention, the degree of polymerization of the aldehyde resin as a binder contained in the ceramic green sheet is preferably 1 Å or more. In the present invention, the butyral of the butyral resin as the binder is preferably 64 mol% or more and 78 mol% or less. In a preferred embodiment of the present invention, after the electrode layer is dried, the electrode layer is dried to contain ethylcellulose having a weight average molecular weight MWL of a ratio of X:(1 -X ) and a weight average amount of MWH.

According to a preferred embodiment of the present invention, a spacer layer is formed on the ceramic green sheet by a pattern complementary to the electrode layer, so that the difference between the electrode layer and the surface of the ceramic green sheet on which the electrode layer is not formed can be prevented. Therefore, laminating the plurality of layer units including the ceramic green sheet and the electrode layer separately can effectively prevent the laminated electrons such as the laminated ceramic capacitors produced, or can be obtained.萜 乙酸 乙酸 种 种 种 印刷 -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10- -10-

The solvent contained in the dielectric paste for forming the spacer layer is a mixed solvent of terpineol and kerosene which has been conventionally used, dihydroterpineol, terpineol, etc., which dissolves the ceramic green sheet as a binder. The butyral resin is soaked, so that the ceramic green sheet is swollen or partially dissolved, causing voids at the interface between the ceramic green sheet and the spacer layer, or cracks or wrinkles on the surface of the spacer layer, laminating the laminate unit, and firing In the laminated ceramic capacitor produced in the following, a void is formed, and a laminated layer unit is formed in a portion in which a crack or wrinkle is formed. In the step of forming a laminate, the laminate is mixed as an impurity to form a laminated ceramic. The reason for the internal defects of the capacitor is that a void is generated in the defect portion of the spacer layer. However, in accordance with a preferred embodiment of the present invention, the dielectric paste for forming the spacer layer contains: a weight containing X: (X) Compared to the ethyl cellulose of weight average molecular weight MWl and the ethyl cellulose binder of weight average molecular weight MW η (select μ W l, MWH and X make X*MWL+(1-X) *MWH become 110,000 to 180,000) and selected from isobornyl acetate, indoline methyl ether, terpine methyl ether, α-fluorenyl acetate, I-dihydrocarvyl acetate, a solvent of at least one of [_ menthone, κ-capped acetate, I-perilla acetate, and I-carvyl acetate, selected from isobornyl acetate, indoline Methyl ether, terpine methyl ether, α-fluorenyl acetate, I-dihydrocarvyl acetate, menthone, I-capry acetate, 1_peracetate and The solvent grouped with carvinoacetate hardly dissolves the butyral resin contained in the ceramic green sheet as a binder, thereby reliably preventing the ceramic green sheet from being swollen or partially dissolved in the ceramic green sheet. The interface with the spacer layer creates voids -11 - (8) 1262516, or the surface of the spacer layer is cracked or wrinkled, so that it is possible to surely prevent lamination of a plurality of laminate units containing ceramic green sheets and electrode layers, and the resulting layer Laminated electronic parts such as ceramic capacitors create voids. Contains: Ethylcellulose containing a weight average molecular weight of MWl of X: (1-X) and ethylcellulose of weight average molecular weight MWH ij (selecting MWL, MWH and X makes X * MWL+ ( 1 -X ) *

M WH is 110,000 to 180,000) and selected from isobornyl acetate, dihydrofurfuryl methyl ether, terpine methyl ether, α_terpine acetate, and I-dihydrocarvyl a dielectric paste of a solvent of at least one of a group of acid esters, I-menthone, I-capped acetate, I-peripate acetate, and I-carvyl acetate, suitable for printing The viscosity is thus printed onto the ceramic green sheet in a pattern complementary to the pattern of the electrode layers to form the desired spacer layer. Further, when the electrode paste for the electrode layer is printed on the extremely thin ceramic green sheet to form an electrode layer, the solvent in the conductor paste dissolves or swells the binder component of the ceramic green sheet, and additionally generates electricity. The body paste may infiltrate into the ceramic green sheet, which causes a short circuit. Therefore, the electrode layer is formed on the additional support sheet, and after drying, the surface of the ceramic green sheet is preferably adhered via the adhesive layer. As apparent from the inventors of the present invention, as described above, when the electrode layer is formed on another support sheet, the support sheet is easily peeled off from the electrode layer, and the same bond as the ceramic green sheet is formed on the surface of the support sheet. The peeling layer of the agent is preferably printed on the peeling layer to form an electrode paste. When the conductor paste is printed on the release layer having the same composition as that of the ceramic green sheet to form an electrode layer, the release layer also contains a butadiene resin of a binder, and the conductor paste -12-1262516

Ο) When a terpineol solvent is contained, the viscous solvent contained in the release layer is dissolved, and the release layer is swollen, or a void is formed at the interface between the portion and the electrode layer, or an electrode layer is formed, and the laminate unit is fired. The problem of the ceramic gap. Since the surface of the electrode layer is cracked or wrinkled, the laminated laminate unit is mixed into the laminate to form a laminated ceramic capacitor, and the defective portion of the electrode layer has a problem of voids. However, according to the present invention, a binder containing ethyl cellulose having a weight average molecular weight M WL of an ethyl molecular weight MWH (矣X is used to make X*MWl+(1-X)*MWH 14.

And the solvent in which I-carvyl acetate is grouped contains almost the butadiene-based resin as a binder, and the peeling layer of the same binder of the ceramic green sheet, even in the body paste, when the electrode layer is formed, Forming the electrode-stopping layer to swell, or partially dissolve, causing voids in the peeling surface, or cracking on the surface of the electrode layer or dissolution of the conductive paste, causing cracks in the peeling layer or voiding in the capacitor 'This part is prone to lack of steps, and there is X: ( lx ) cellulose for the internal defects of the impurity shape.

Therefore, when the conductive layer is formed on the release layer, the wrinkles of the separation layer and the electrode layer can be effectively prevented, which can effectively prevent -13- (10) 1262516 Laminated electronic components such as laminated ceramic capacitors have voids. [Effects of the Invention] According to the present invention, the bonding agent contained in the layer adjacent to the electrode layer is not dissolved, and the laminated ceramic can be surely prevented. The electronic component is short-circuited and provides a conductive paste excellent in printability.

A spacer layer is formed. As described above, a spacer layer is formed on the surface of the ceramic green sheet in a pattern complementary to the pattern of the electrode layer, and a step difference can be prevented between the surface of the electrode layer and the surface of the ceramic green sheet on which the electrode layer is not formed, and thus the lamination is respectively included. The ceramic laminate also has a plurality of laminated units of the electrode layer and the electrode layer, which can effectively prevent deformation of the laminated electronic component such as the laminated ceramic capacitor, and can effectively prevent delamination. As described above, selected from the group consisting of isobornyl acetate, indoline methyl ether, terpine methyl ether, α-β acetate, I-dihydroacetic acid acetate, I-menthone, The solvent grouped with I-mercaptoacetate, I-peripate acetate and i-carvyl acetate hardly dissolves the butyral resin contained in the ceramic green sheet as a binder, and therefore, It is indeed prevented to form the solvent contained in the dielectric paste for the spacer layer, causing the ceramic green sheet to swell, or partially dissolve 'or create a void at the interface between the ceramic green sheet and the spacer layer, or the interval -18- (15 ) 1262516 The surface of the layer is cracked or wrinkled.

In the present embodiment, the dielectric paste for the spacer layer is prepared in the same manner as the dielectric layer paste for the ceramic green sheet except that a different binder and solvent are used. Next, after the electrode layer, the electrode layer and the spacer layer are dried, a laminated ceramic green sheet and an electrode layer or a laminate unit of the electrode layer and the spacer layer are formed on the supporting sheet.

1262516 Next, a ceramic ceramic capacitor is fabricated by mounting a necessary electrode or the like on the ceramic green wafer after calcination. According to this embodiment, it is intended to contain a binder containing ethyl cellulose having a weight average molecular weight of MXL in a weight ratio of X: and ethyl cellulose having a molecular weight of MW η (selecting MW!_ and X for X) *MWL+(1-X) *MWH becomes 145,000~21 and is selected from isobornyl acetate, dihydrofurfuryl methyl ether, terpine base acetate, I-dihydrocarvyl Conductive paste of a solvent grouped with acetate, I. menthone, acetate, I-peripate acetate and I-carvyl acetate, printed in a predetermined pattern to contain On the ceramic green sheet of the aldehyde resin, the electrode layer is selected from the group consisting of isobornyl acetate, indoline methyl ether, terpineyl mercapto acetate, and I-dihydrocarvyl Groups of acid esters, I-menthone, acetate, I-peresa acetate, and sulphonic acid acetate do not dissolve the shrinkage resin contained in the ceramic green sheet as a binder, and therefore, conduct electricity. When the body paste is printed to a very thin ceramic green body to form an electrode layer, the solvent contained in the ceramic green sheet can be effectively prevented from being contained in the solvent contained in the conductive paste.
